The emergence of smart IT, the rapid development of information and communication (ICT) technology, new network communication technology and new forms of production and consumption. Among the newly created industries, the smart grid industry can be seen. The smart grid industry is one of the ways to solve the environmental problem, which has been a global issue since the past. Smart Grid is a systematic structure of standards created by national and international standards bodies. The standard shows a real-time two-way communication between power providers and consumers, similar to that of smart homes. Smart homes are contributing to the convenience and safety of ICT technology as home appliances existing in homes are connected in various networks and smart home services are popularized. However, as the convenience of users generated through the network increases, various problems such as invasion of personal information, data forgery, and hacking occur.

On the other hand, according to the security requirements of the smart grid, smart grid can recover itself in the event of an IT disaster, but smart home has a limitation that lacks automatic recovery system. Therefore, based on the smart grid standard system, a recovery technology for IT disasters in the smart home is required.

The present invention can be applied to external networks such as denial of service attacks, data forgery, unauthorized access, device duplication, device intrusion, illegal control command transmission, sniffing, malware infection, information leakage, and privacy invasion to a network or various device devices. It is to provide a smart grid-based smart home system and IT disaster recovery method that restores to its original state in a short time when an attack or disaster occurs and power is no longer supplied.

Referring to FIG. 1, the smart grid-based smart home system according to an embodiment of the present invention includes an operations domain 10, a service provider domain 20, and a customer domain. 30) and a Distributed Energy Resource (DER) domain 40.

The operation domain 10 is responsible for the overall operation of the smart grid to provide and manage the power provided from the power transmission domain to the customer domain 30, the energy management system (EMS) Actor (13) And a meter data management system (MDMS) actor 11.

The energy management system actor 13 performs a function of controlling power to be produced and transmitted according to the power demand of the user. For example, the energy management system actor 13 may perform a function of preventing power waste by identifying power demand and distributing power according to the identified power demand.

The meter data management system actor 11 collects and stores meter information from the customer domain 30, provides the collected meter information to a related authority, and verifies data using the log information of the meter actor 37 to verify and use the data. Do this. For example, the meter data management system actor 11 collects meter information including energy usage, energy production amount, and the like from the meter actor 37 of the customer domain 30 in advance and attacks the meter actor 37 with an attack. If a problem occurs, the original data can be analyzed to help solve the problem.

The service provider domain 20 performs a function of providing a power service to the customer domain 30 that substantially communicates in the smart home system, and the customer information system (CIS) actor 21, billing. (Billing) actor 23 and Home Manager actor (25).

The customer information system actor 21 is a system for managing personal information of a customer, and among the data generated by the user using the smart home appliance in the smart home system, the data including the user's personal privacy is leaked due to various events. It performs a function to prevent it.

The billing actor 23 performs a billing function of the customer such as billing and billing management of the customer, including billing and payment processing. For example, the billing actor 23 prevents monetary damage from being generated by hacking caused by external or internal events generated when the customer uses power through the smart home appliance in the smart home system. To perform the function.

The home manager actor 25 installs equipment that interacts between the customer domain 30 and the smart grid and performs energy management functions.
